Vedclass · Answer

(C) Magnetic flux is defined as the measure of the total magnetic field passing through a given surface area.Mathematically,for a uniform magnetic field $\overrightarrow{B}$ passing through a surface with area vector $\overrightarrow{A}$,the magnetic flux $\Phi$ is defined as the scalar product (dot product) of the magnetic field vector and the area vector.Therefore,$\Phi = \overrightarrow{B} \cdot \overrightarrow{A} = BA \cos 	heta$,where $	heta$ is the angle between the magnetic field vector and the normal to the surface area.Thus,the correct expression is $\overrightarrow{B} \cdot \overrightarrow{A}$.
